In the presence of an iridium compound, an imine of the following formula (1):
wherein R1, R2 and R3 are each, identical to or different from one another, a hydrogen atom or a non-reactive organic group, where R1 and R2 may be combined to form a ring together with the adjacent carbon atom, is reacted with a diazoacetic acid derivative of the following formula (2):
N2CHR4 (2)
wherein R4 is a cyano group, an alkoxycarbonyl group, a carbamoyl group or the like, to yield an aziridine compound of the following formula (5):
wherein R1, R2, R3 and R4 have the same meanings as defined above. The process can easily and efficiently produce aziridine compounds.
在铱化合物存在的情况下,下式(1)的亚胺:
其中 R1、R2 和 R3 各自为相同或不同的氢原子或非反应性有机基团,其中 R1 和 R2 可与相邻碳原子结合形成一个环,该亚胺与下式(2)的重氮乙酸衍生物反应:
N2CHR4 (2)
其中 R4 为氰基、烷氧羰基、氨基甲酰基或类似基团,生成下式(5)的氮丙啶化合物:
其中 R1、R2、R3 和 R4 的含义与上述定义相同。该工艺可以方便、高效地生产氮丙啶化合物。
